Optimization of underground mine backfill with novel use of backfilled stope

加拿大采矿业开采矿山和生产增值矿产品的能力将取决于矿山运营、环境和可持续性以及能源效率的优化，以确保持续的竞争力。可持续性必须是从勘探到运营和关闭的所有采矿项目的一部分，这意味着使用清洁技术，减少能源消耗，减少向环境排放和污水。因此，必须使用先进技术来提高从勘探到最终产品的效率。 由于加拿大地盾的深度极深，应力极高，因此深井作业需要在采矿和加工方面采取创新方法。京都雅阁的实施进一步强调了矿山回填技术的优化，并欢迎矿山回填采场发电的独特提议。这可能为工业和偏远社区带来重大的经济收益。 考虑到上述优先事项，申请人的长期目标和研究计划涉及开发和整合优化加拿大矿山运营的新技术。这些包括膏体填充、岩石填充、凝胶填充和新的泡沫填充系统的开发，并有助于优化泥浆输送和减少管道磨损，以及新颖的钻探和岩石破碎技术，如微波辅助机械破碎岩石。此外，申请人的研究涉及从活跃和废弃矿山中探索新的可持续和环境能源。

The Canadian mining industry's ability to exploit mines and produce value-added mineral products will depend on the optimization of mine operation, environment and sustainability, and energy efficiency to ensure continued competitiveness . Sustainability must be part of all mining projects from exploration through operation and closure, which implies the use of clean technologies, reducing energy consumption and reduction of emission and effluent discharge to the environment. Therefore, use of advanced technologies to improve efficiencies from exploration to final product is a must. Due to the extremely high stresses associated with great depths in the Canadian Shield, deep mine operations require innovative approaches in both mining and processing. The implementation of the Kyoto Accord further emphasizes the optimization of mine backfill technology and welcomes the unique proposal of generating energy from mine backfill stopes. This could result in major financial gains for industry and remote communities . Considering the above priorities, the applicant's long term goal and research program involves the development and integration of novel techniques for optimization of Canadian mine operations. These include paste fill, rock fill, gel fill and the development of new foam fill systems, and to contribute to optimization of slurry transportation and reduction of the pipe wear together with novel drilling and rock breakage techniques such as microwave assisted mechanical breakage of rocks. Furthermore, the applicant's research involves exploring new sustainable and environmental energy resources from both active and abandon mines.
